Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power transmission, and particularly relates to a power transmission line auxiliary equipment suspension device based on a unmanned aerial vehicle. BACKGROUND

[0002] The existing method for hanging warning lights on power transmission and distribution lines generally uses an insulating operating rod to hang warning lights for relatively low lines, and uses a live working method to hang warning lights for relatively high power transmission and distribution lines, which is very risky and very cumbersome in the operation process and has low operation efficiency. The use of unmanned aerial vehicles to hang warning lights on power transmission and distribution lines can avoid such operation risks and greatly improve operation efficiency, and is no longer affected by the height and terrain of power transmission and distribution lines.

[0003] Traditional power transmission line warning light installation relies on manual live working or single mounting by unmanned aerial vehicles, and has problems such as low efficiency, high risk and high cost. Although the existing technologies such as insulating boom trucks and unmanned aerial vehicle auxiliary mounting have been improved, they are still limited by single light mounting mode and cannot meet the large-scale warning demand, and have poor adaptability to complex terrains. For example, the invention patent 202111402123.4 discloses a high-altitude warning light hanging device based on a unmanned aerial vehicle. First, the short foot of the warning light is clamped into the horn-shaped guide slot of the fixed arm, and the long foot is inserted into the vertical downward dropout slot of the dropout arm, and the edge of the slot is protruded to prevent accidental falling. Then, the warning light fixing seat is installed on the crossbeam of the unmanned aerial vehicle fixing seat through the connecting assembly, and the unmanned aerial vehicle fixing seat is tied to the unmanned aerial vehicle leg through the supporting side arm and the isolation block. When the unmanned aerial vehicle flies over the power transmission and distribution line, the wire contacts the warning light to generate downward pressure, so that the long foot is dropped out of the dropout slot, and the double feet of the warning light are closed and hung on the wire under the action of the elastic force. Finally, the unmanned aerial vehicle moves downward, the short foot slides off the device from the horn-shaped guide slot, and the safe hanging of the high-altitude warning light is completed. However, the device only supports single light hanging, cannot expand the multi-light synchronous hanging structure, needs multiple round trips for long-distance operation, relies on precise pressure of the guide wire for dropout, and is prone to dropout failure due to strong wind or guide wire shaking. In addition, the dropout slot protrusion has high precision requirement, and the reliability decreases after wear. SUMMARY
